Need some help

[SnoopMonkeyMonk]

I'm 21 years old and is considering buying the 540i sometime this month. I already order the M5 left side muffler and gonna order the bumpers and wheels later on probably even before I have the car. But the 540i wasn't my first choice as my next vehicle, the GS400 was. Now I'm even considering the 2004 Maxima SE as a candidate as well. Why not just buy a M5 you might ask. Cause I'm only 21 and don't have a deep wallet like all of you do. And also, I want an automatic as I been driving and modding my Honda Prelude VTEC which is manual for the past 4 years. I'm just too lazy to drive standard now. I'm getting sick of teens in their Civic or Integra thinking they have the fastest car on the road always wanting to race me at the light or on the highway and the police giving me tickets for bs stuff. So when this car is sold, I'll be buying either one of these car.

I already ruled out the 2004 Maxima cause it's front wheel drive but the optional rear bucket seats and sky view sunroof keeps it on my list. I also heard rumors that there might be an AWD version coming out later on since this car is built on the same platform as the Murano. But I can't wait that long. And I also owned a 95 Maxima SE till about 3 days ago when I sold it. I loved that car and was gonna keep it as a beater but I got an offer that I couldn't refused for it. That's why this car is still on my list.

The BMW is a great car but I'm just worried about maintenance cost later on. The Lexus GS400, well I don't know much about this car cause I've been hanging around the BMW forum lately and trying to sell my Prelude at the same time. So this is where I need some help. I need to know the good points and bad points of the 540i ASAP cause I might deposit on a 540i later on next week. Thanks
